Patented Apr. 14, 1936 UNITED STATES PATENT OFFICE 2 Claims.

One object of this invention is the provision of a registering bank soconstructed that it will receive and selectively register nickels,dimes, and quarters, the construction and operation of the bank being sodeveloped and attained that the method of attaining the said object issimple and accurate.

The above and other objects will become apparent in the descriptionbelow, in which characters of reference refer to like-named parts in theaccompanying drawing.

Referring briefly to the drawing, Fig. 1 is a perspective View of thebank; Fig. 2 is a fragmentary plan view with a portion of the roofremoved; Fig. 3 is a cross-section taken on the line 3 3 of Fig. 2; Fig.4 is a cross-section taken on the line 4-4 of Fig. 3; Fig. 5 is across-section taken on the line 5-5 of Fig. 4; Fig. 6 is a view similarto Fig. 4 illustrating the various elements in position after a quarterhas been deposited and registered; Fig. 7 is a cross-section taken onthe line '|-'l of Fig. 3; Fig. 8 is a. plan view of one of the registerdials; Fig. 9 is a view similar to a portion of Fig. 6 showing theposition of the pawl lever after a nickel has been registered; and Fig.10 is a view similar to Fig. 9 after a dime has been registered.

Referring in detail to the drawing, the numeral It! represents thehousing of the bank having an opening I l on one side which is closed bya slide door l2 provided with a handle l3. At the top three slots l4,l5, and 16 are provided to expose the dial numbers which show the amountof money deposited. The front wall of the housing is slotted at H andI8, the former to permit sidewise movement of a tongue l9 rigid on anarm 20, and the latter is the coin slot provided with an arched lip 2 I.

Rotatably mounted on one side of the ceiling is a disk 22 provided atone point of its periphery with a pair of teeth 23. A gear 24 havingteeth 25 is rigid with the disk 22. A spring band 26 is attached on itsedge to the ceiling and provided at one end with a nose or pawl 21normally urged against the teeth 25, and at the other end with a.similar nose 21a normally urged against the tooth 29 of a disc 28.Adjacent the disk 22 the disk 28 having teeth 29 is rotatably mounted inthe ceiling, the teeth 23 of the disk 22 engaging the teeth 29 onceduring every revolution of the disc 22. The disk 22 is provided on itsupper face with the dial number shown in Fig. 8, and the disk 28 isprovided with the dial numbers shown fragmentarily in Fig. 2.

A slide arm or member 30 is slidably mounted againstthe front wall ofthe housing, being provided with an upper extension 3| and a lowerextention 32. The latter is bent to provide a stall 33 which normallylies with its entrance against the coin slot 18. A cut-out shoulder 34is provided at the front part of the stall 33. A coiled spring 35normally urges the member 30 to the right (Figure 2), being attached atone end to the member 38 and at the other to an upright wall 35. Arocker arm 31 is pivotally at- 10 tached at 38 to the member 30, andnormally its pivoted end lies adjacent the wall 36. Near the other endof the arm 31 a tongue 39 extends at right angles from the member 3'!and normally rests on the shoulder 34 of the stall 33. A relal5 tivelylong and wide pawl 49 extends from the arm 3'! at right angles to thisarm and the tongue 33, and above the pawl 43 and spaced therefrom by aslot 4 I, a second relatively narrow and short pawl 42 extends in thesame manner from the arm 20 3?. At a point nearer the pivot 38 a thirdpawl 43 extends in the same manner from the arm 31, the pawl 43extending outward from the arm 31 substantially the same distance as thepawl 40. The pawl 42 is of such length that the path of 25 its end inbeing moved in the plane of gear 24 to intersect the periphery of thegear 24, intersects the same to such adepth that the pawl 42 turns thegear 24 through a distance of two teeth, in thus passing the gear 24.The pawl 49 30 is of sufficient length (greater than that of the pawl42) that the same sliding movement of the arm 3! with the pawl in theplane of the gear 24 will cause the gear 24 to rotate through fourteeth. The pawl 43 is so positioned intermediate 35 the arm 3'! that itcan turn the gear 24 through only one tooth whenever it moves in theplane of and strikes this gear. Although it would turn the gear throughadditional teeth if it could continue its travel, it is prevented fromdoing so by the extension 32 striking the side wall of the housing, theextension 32 serving as a limit stop from the slide. A spring 44normally urges the arm 31 down on the left (Figure 4). A wall 45 havinga slot 46 therein divides the deposit com- 45 partment 47 from theremainder of the housing interior.

The operation of the device is as follows: When a-dime is inserted intothe slot [8 it enters the stall 33 and in doing so raises the tongue 3950 and hence the left-hand end of the arm 31. The latter will thus beraised just a sufiicient distance to cause the pawl 42 to rise into thepath of the teeth 25 (Figure 10). Then the arm 30 is slid to the right(Fig. l) to the left (Fig. 6, Fig.

10), to its extreme position where it is stopped by the extension 32striking the side wall of the housing. In doing so, the pawl 42 willrotate the gear 24 a peripheral distance of two teeth, causing the disk22 to turn the same angular distance and change the number in the slotsl5l5 by adding thereto, as is apparent in Fig. 8. When the slide 30 isin its said extreme position, the stall 33 stands directly over the slot45, and the coin drops into the compartment 41. If, instead of a dime, anickel is inserted in the slot l8 and the same operation repeated, thearm 31 is raised upon insertion of the nickel to a higher position (Fig.9). In this position, with a nickel in the stall 33, the pawl 42 risesabove the level of the teeth 25, so that upon movement of the slide 30the pawl 42 does not strike the teeth 25. Instead, the slot 4| (Fig. 9)is raised into the level of the teeth 25, and as the slide 30 and withit the arm 31, is slid to the left the pawl 43 turns the gear 24 adistance of one tooth, (since the intermediate position of the pawl 43lengthwise of the arm 3! permits the pawl 43 to turn the gear 24 throughonly one tooth before it is stopped by the extension 32 striking thehousing wall) thus adding 05 to the total in the slots l5|6. When aquarter is inserted into the slot 18 and the operation repeated, the arm3! is raised still higher, into the position shown in Fig.

6. In this position the pawls 40 and 42 are also inclined further to theright (Fig. 6), so that the engagement of the pawl 40, which is nowraised into the path of teeth 25, turns the latter a distance of fourteeth, and in addition the pawl 43, at the end of the sliding movement,turns the teeth 25 a distance of another tooth, so that "25 is added tothe total in the slots l5i6. When the gear 24 has made a completerevolution, a l is added in. the slot l4, since the 24 will have rotatedthe gear 28 through two teeth by engagement once every revolution of theteeth 23 with the gear 28; thus registering the dollar total.

As the mechanism for locking the door 12 upon insertion of the firstcoin in the bank, and for opening the same upon the accumulation of agiven total sum, forms no part of this invention, the detaileddescription of the same has been omitted.

Obviously, modifications in form and structure may be made withoutdeparting from the spirit and scope of the invention.

I claim:

1. In a register bank adapted to receive coins of various denominationsand having a gear mounted therein and a registering dial operated bysaid gear upon rotation of said gear, said bank having a coin slot forthe insertion of coins into the bank, a slide mounted behind said slotand having a stall adapted to receive the inserted coins, a rocker armpivotally mounted at one end of said slide and having its free endnormally resting against one end of said stall, a resilient means forurging said free end against said stall, a wall rigid with the banklying adjacent the other end of the stall, the inserted coin passinginto said slot and pushing the free end of said arm away from saidstall, a larger coin pushing said free end a greater distance away fromsaid stall than a smaller coin, pawls on said free end adapted to beselectively pushed into the plane of said gear according to the size ofthe coin, said pawls lying at substantially right angles to said arm andbeing of varying lengths, the longer of said pawls when thus pushed intothe plane of said gear and upon sliding of said slide and arm towardsaid gear causing a relatively deep intersection of the path of saidlonger pawl with the periphery of said gear so as to rotate said gearthrough a relatively greater arc, the shorter of said pawls similarlycausing a relatively shallow intersection with the periphery of saidgear to rotate said gear through a relatively shorter are upon slidingof said slide and arm toward said gear.

2. In a bank adapted to receive coins of varying denominations andhaving a gear mounted therein and a registering dial operated by saidgear upon rotation of said gear, said bank having a coin slot for theinsertion of coins into the bank and a rigid wall adjacent one end ofsaid slot, a slide mounted behind said slot and having a rocker armpivoted at one end thereon, the free end of said arm having a pair ofpawls normally lying adjacent the other end of said slot and lying in aplane at right angles to the arm and having a slot therebetween, one ofsaid pawls being of greater length than the other, a third pawl on saidarm in a plane parallel with the first-named plane and intermediate thelength of said arm, said free end of said arm normally traveling in apath adjacent the plane of said gear upon sliding said slide, means fornormally retaining said free end of said arm in said position adjacentsaid slot, the insertion of a coin of small diameter through said coinslot causing said coin to push said free end of said arm a shortdistance beyond the end of said coin slot and the shorter of said pawlsinto the plane of said gear so that subsequent sliding of said slide andarm will cau e said shorter pawl to rotate said gear through an arc, theinsertion of a coin of next larger diameter through said coin slotcausing the latter coin to push said free end of said arm a greaterdistance beyond the end of said coin slot and the slot between saidpawls and also said third pawl into the plane of said gear so thatsubsequent sliding of said slide and arm will cause said third pawl torotate said gear through an arc, the second named are being shorter thanthe firstnamed arc, a limit stop to the slide movement of said slide,the intermediate position of said third pawl on said arm causing saidthird pawl to reach the end of its slide stroke after rotation of saidgear through a shorter arc than said first-named arc, the insertion of acoin of still larger diameter through said coin slot causing the lattercoin to push said free end of said arm a still greater distance fromsaid coin slot so that upon subsequent sliding of said slide and arm thelonger of said pawls will cause said longer pawl to rotate said gearthrough an are greater than said first-named arc and at the same timesaid third pawl will rotate said gear through an additional arc of thesame length as said secondnamed arc.
